Intelligent computer assisted instruction (CAI) systems are exemplified by several tutorial systems including Tutor-SCHOLAR, Map-SCHOLAR, NLS-SCHOLAR and SOPHIE. The original SCHOLAR program structure made it possible to model the way human tutors interact with students. Further analyses of tutoring and teaching strategies led to the development…

NLS-SCHOLAR is a prototype system that uses artificial intelligence techniques to teach computer-naive people how to use a powerful and complex text editor. It represents a new type of computer-assisted instruction (CAI) system that integrates systematic teaching with actual practice; i.e., one which can keep the user under tutorial supervision…
